桥梁设计多采用箱梁连续结构,在箱梁的施工中也大多采用现场预制和安装的作业方式。箱梁的安装作为桥梁施工中较为关键的施工工序,也是桥梁安全施工中的一项重要工作,施工方需结合项目的实际特点和规范要求,制定详细的施工方案,并做好在施工过程中的组织工作,确保桥梁施工的安全性。文章以南水北调辉县段南陈马东南公路桥箱梁施工为例,对箱梁安装的设计要求和施工工艺进行改进,具有较好的推广应用价值。
Bridge design and more use of continuous box girder structure, box girder construction are mostly prefabricated and installed on-site operation. The installation of box girder is a key construction process in bridge construction. It is also an important work in bridge safety construction. Construction parties need to formulate detailed construction plans in combination with the actual characteristics and specifications of the project and do a good job in the construction process The organization of work to ensure the safety of the construction of the bridge. Taking the construction of south-east-south highway bridge box girder in Huixian section of South-to-North Water Diversion Project as an example, the design requirements and construction technology of box girder installation are improved, which has a good application value.
